Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ * The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
+ * can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
+ * the LOCAL/current NODE. REMOTE means it is attached to a different
+ * node.(TBD - Need a way to treat ROUTER boards.)
+ *
+ * There are 2 different structures to represent these boards -
+ * lboard - Local board, rboard - remote board. These 2 structures
+ * can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
+ * Figure below). The first byte of the rboard or lboard structure
+ * is used to find out its type - no unions are used.
+ * If it is a lboard, then the config info of this board will be found
+ * on the local node. (LOCAL NODE BASE + offset value gives pointer to
+ * the structure.
+ * If it is a rboard, the local structure contains the node number
+ * and the offset of the beginning of the LINKED LIST on the remote node.
+ * The details of the hardware on a remote node can be built locally,
+ * if required, by reading the LINKED LIST on the remote node and
+ * ignoring all the rboards on that node.
+ *
+ * The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
+ * First board info on the remote node. The remote node list is
+ * traversed as the local list, using the REMOTE BASE ADDRESS and not
+ * the local base address and ignoring all rboard values.

+ * Each BOARD consists of COMPONENTs and the BOARD structure has
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error
+ * information specific to the COMPONENT is present in the respective
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ *
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.
